How can PHP be used to create a chat feature for a CMS?

To create a chat feature for a CMS using PHP, you can utilize AJAX to send and receive messages without refreshing the page. You will need to create a database to store chat messages and use PHP to handle the backend logic for sending and retrieving messages. 

<?php
// Connect to the database
$conn = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve chat messages from the database
$query = "SELECT * FROM chat_messages ORDER BY timestamp DESC";
$result = $conn->query($query);

// Display chat messages
while($row = $result->fetch_assoc()) {
    echo $row['username'] . ": " . $row['message'] . "<br>";
}

// Close database connection
$conn->close();
?>
